Be it known that I, .Ro ER r S. Bram, a citizen of the. United States, residing at'New York, in the county of New'YorksandiState certain new and useful Improvements in Eyeglasses, of'which" ofNew York, have invented the following is a full, clear, and"'exact*de scription, such as willenableothers skilledin the art to which it appertainsfto malre and the like. g e

One of the objects thereofjis to provide efficient and practical means for cidental detachment of eyeglasses;

Another object is to rovide means of the above type which shal be readily placed in This invention relates and sired.

Another object is to provide means adaptcorrectpositioning of the glasses or lenses with respectto-the eye. art-obvious and in part pointed out hereina er.

. he invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts,which will be exemplified in the device hereinafter dedrawing use, the entire device is scribed and the scope of the application of hich -will be indicated in t e following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of my invention, Figure 1 is a plan of the same. Fig. 2 is a front elevation of the same. Fig. 3 is a detail perspective of a connecting "member with stopping means formed therelar parts throughout the several views of the s. 1' 1 This invention will be most readily understood-if the following facts be borne in mind With many types of eyeglasses, and particu-:

note that when the glasses are brushed or struck from the face, which is the most com- 'mon way in which the same are broken, it is 'in the vast majority of cases occasioned by a blow or thrust exerted against the outer endl alinement. of the-lenses depends to a considerable extent upon the distance at which the nose-pads are spaced, and thus the correctnesls of the alinement depends upon the exact position in which the glasses areplaced. The above and .otherdefects are remedied and many positive advantages attained in ter described,

The remaining arm of this lever, which is securedltheretomin any desired manner, is in this illustrative embodiment formed of a spring 12,si1nilar to the part .9 and rovided in like manner with a nose-pad. T e spring portions 9 and 12 are secured to the corresponding levers by any desired means, as soldering, riveting, or otherwise. v
